IGNITION AAND PROPULSION TUBE.

Applicatienv led July 15,

To all whom t may concern.:

Beit known that I, CHARLES A. BRAUNGER, a citizen of the United States, and a resident fof Elizabeth, in the county of Union and State of New Jersey, have invented a new and Impro-ved Ignition and Propulsion Tube, of which the following is a full, clear, and exact description..

This invention relates to an ignition and propulsion tube for bombs or the like.

The object of this invention is to provide j in conjunction with a missile containing an explosive charge a device containing means for igniting the explosive charge,means for propelling the missile and operating the igniting means, and means for controlling the flight of the missile. y

This object is accomplished by providing a tube containing igniting means for the explosive charge in the missile and that may be operated by a propelling means alsoconi tained in the tube and having a guiding mea-ns which cooperates-with the guide in conjunction with the missile thrower.

This and other objects ofthe invention will be more clearly understood from thev following detailed description and accompanying drawings.

Figure 1 is a cross section through the igniting and propelling tube placed'in position in a bomb and mounted on the guide in conjunction with the missile thrower; and

Figure 2 is abside elevation of the igniting y and propelling tube.

Referring to. the Aabove-mentioned drawings, 10 is the recoil tube of a missile thrower, described in my copending application, Serial No. 485,058, filed July 15, 1921, and entitled Missile thrower. A projection 11 which serves as a guide for controlling the flight of the missile is provided in conjunction with the recoil tube 10. A firing pin 12 is slidably mounted in the opening 13 which extends through the projection 11.

A tube 14, which is shown of cartridge shape, has a number of chambers therein.I This tube need not be of cartridge shape but this is mentioned as one of the preferred shapes. A chamber' 15 is provided in the upper end of the tube for containing ameansy 16 for igniting the charge'l? contained in the chamber 18, an opening 19 being provided in the end of the tube to connect the chamber 15 to the interior ofthe bomb. This means for igniting the charge 17 may' 1921. Serial No. 485,059.

consist of quick match, fuse or some other means such as paste that is sometimes used for igniting charges.v

Located just below the chamber l5 is another chamber 20. This chamber is for containing the propelling charge, which in this case is shown to be a revolver cartridge 21 having a, cap 22.v Located in the top of .the

onator in alinement with the opening extending through the projectionll.

In the base of the tube is a chamber 24.

This chamber is so shaped that it fits the projection 11 of the missile thrower and cooperates with the same to direct the Hight of the missile A collar 25 is provided on the base of the tube and the outside portion 26 just above the collar is threaded so as t0 engage with bomb 18.

The operation of lthis device is as follows:

The tube is forced intothe bomb containing the explosive charge until the thread 26 the threadedv opening 2'( in the has engaged in the threaded opening 27 in the bomb, then, if rey uired, a revolver cartridge which has the ulletA removed may be inserted inthe chamber 20 and the device is ready for use. bomb the firing pin is withdrawn and the chamber 24 is fitted over the projection 11 of the missile thrower.l Proper aim is taken and the iring pin operated by any means to detonate the detonator 22. This explodes the propelling charge in the cartridge 21 which forces the metal projection 23 against the igniting means 16 and operates the same. The igniting means finally ignites thejcharge and gives the desired explosion. This igniting means may be suited to period.

Claims:

1. In combination with a missile containingan explosive charge, a propulsion and ignition tube of the class' described, comprising tube means adapted to` be removably inserted into the missile, means for igniting When it is desired tofire the the required time j the missile explosive charge carried by the tube, means located in the tube' for firing the ignition means, a propelling charge contained in thev tube, means operated by the propelling charge to ignite the means tor .firing the missile explosiv`-charge igniting means, and guiding means in conjunction With the tube.

2. In combination With a missile containing an explosive charge, a` propulsion and ignition tube of the class described comprising tube means adapted to be removably inserted into the missile, embedding it in the missile explosive charge, having a chamber therein lor receiving a propelling charge, means carried by the tube for igniting the l missile explosive charge, means fired by the propelling charge forl tiring the igniting means, and internal guiding means provided in the tube. v l

3. In combination with a missile containing an explosive charge, an ignition and propelling tube of theclass described, comprising tube means for removably inserting into Vthe missile. having 'a chamber for the means chamber 'forthe propelling charge, guidina means enclosed Within the base of the tube,

yand means for missile.

5. In combination with a missile containing an explosive charge, a propulsion and ignition tube of the class described, comprising tube means for removably inserting into the missile to embed the same in the missile explosive charge, means for igniting the missile explosive charge carried by the tube, means located in the tube for firing said igniting means, a propelling charge contained in the tube, means interposed between the propelling charge andA said tiring means to fire the latter, guiding means in conjunction With the base of the tube, and means for retaining said tube in position in the missile.

p 6. In combination with a missile containing an explosive charge, a missile throiver having missile guiding means, a propulsion retaining the tube inv the and ignition tube of the class described comprising tube means for removably inserting into the missile to embed in the explosive charge, means Jr'or igniting the explosive charge carried by the tube, fuse mea-ns located in the tube and associated With the means for igniting the explosive charge, means yfor firing the fuse, a propelling charge carried by the casing and co-operating with the fuse, firing means to operate the same When the propelling charge is fired, percussion means in conjunction with the propelling charge for firing the same, 4means for retaining said tube means in position, and means in the base of the tube to serve as guiding means.
